Check my Fuelly and you'll see that I regularly get around 36-37mpg but since having a few days away in Scotland I've hit 40.4mpg for the past 230 miles. I know the DIS isn't fully accurate but it's never far off when you put the numbers in Fuelly.
Not bad for a 121k car. Fresh oil change as it had gone through a little over the months lately. I suppose if I was running air con then it would be a little lower but it needs regassed.
I wasn't completely driving like a granny either, a good few overtakes on the A75 with a boot-full and some spirited driving today. Awesome car. Awesome, awesome!
